Preformed drainage outlets manufactured from TPE compound for through walls and drainage holes next to parapets using bitumen based waterproofing membranes. Most suitable for liquid two-coat bitumen, felts and hot melt.

These TPE through-wall fittings are an alternative design and manufactured with a ribbed rather than perforated profile across the whole flange/border. Apply one coat of waterproofing membrane and install the outlet. Allow the still tacky membrane to ooze through the perforations and then apply the second coat of bituminous membrane to achieve an over-and-under bond.

Drainage outlet is protected by having additional layer and fully sealed. A round or square leaf guard can be inserted into mouth of outlet once installed. Always use a compatible primer both to the outlet shape and the waterproofing membrane before installation.
